This invention relates to grain harvesters provided with a binders car.

My improvements consist inV the `details of construction and arrangement oi' various parts of the machine, which Will be more 4specifically pointed out inthe subjoined description and claims.

v 'I o enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The main frame, marked A in the annexed drawings, is constructed of strong timbers rmly bolted together, of rectangular shape,

and hung upon the journals of the axle C of the supporting-wheel B by means of stout hangers A1. It is provided with a drivers seat, A?, and a draft-pole, A3, pivoted to its forward-end, about in line with Wheel B.

y The frame-Work for the support of the grainplatform and conveyingapron, and their operative mechanisms, is rigidly secured to the main frame'A, and may be of substantially the form shown. The outer side of the grain-platform is supported upon a small Wh eel, D', and also provided with the ordinary divider D. y

B' is a large bevel-Wheel, fastened upon one side of the driving-wheel B, and gearing into a small bevel-pinion, El, hung loosely upon the shaft E. The bevel-pinion is provided with projections upon its hub adapted to engage with a sliding'olutch-box, E, which latter is arranged upon the main shaft by a feather or spline, and thrown in and out of gear by the driver by means of an elbow-lever, E3, which is fulcrumed on the main frame. To assist in throwing the clutch-box in gear I employ a spiral spring, e, encircling theshaft and bearing with one end against a shoulder thereon, and with the other against the rear of the clutch-box. It will be understood that the shaft is revolved only when the clutch-box is in gearwith the projections oi' the bevelpinion.

At'E4 the-shaft E isprovided with a crank,

and by means of it drives the cutter-bar F V throughr the pitman F2 and vibrating arm or lever F1. The latter oscillates on a stud, f, secured to a lug, f1, projecting from -the main frame, and is connected at its forward end to the cutter-bar by a link, f2, and at the rear end attached by a suitable joint to the pit- The finger-bar G is made of Wood, strengthened by iron bars g g, placed upon its upper and under side, and rmly bolted thereto by the bolts which secure the ngers G A portion, H, of the grain-platform, directly in rear of the finger-bar, is made permanent, as shown, but the larger part, H1, is constituted of an endless apron, composed of slats and endless chains, upon which the former are fastened, the Whole arranged to revolve over suitable sprocket wheels H2 H2, which are mounted upon transyerse shafts H3 and H4.

By reference to Fig. 2, it Will be seen that the grain-platform is concave upon its upper surface, gradually rising from the finger-bar upward to its rear end, which is on a level, or nearly so, with the upper surface of the conveying-apron. Thus, it forms the segment of a circle, or nearly so, having the axis of the reelas its center. To preserve the concavity of theapron part of the platform, the ends of its slats with the chainsf-projectv and' travel under the lower" edge, or acasingthereof, of "the'perrnanent segmental side-board H5 of the platform, which may be lined with metallic strips h, onarmed in other suitable manner, to prevent too rapid wear. Y Y l H4, which extends behind the main frame, and carries at its ovcrllun'g endfa bevel-wheel, H5. The latter is driven by a bevel-wheel, I2, upon the shaft I, which is arranged at right angles` to the shaft H4, and above,fand parallel to, `the shaft E, from which it Vderives'its' :motion through an endless chain, I1, passing over sprocket-wheelsonlthe respective shafts, as indicated in Fig. l.

, If preferred, motion may be communicated from -the'main shaft tothe shaft I through intermediate gear-wheels.

Krepresents the reel. Its shaftj'issupported at its outer end in a suitableA bearer, erected on the frame-work of the grain-platform, and at its inner endl in bearingson a post on the main frame. It is d riven directly from the driving-axle through the medium of sprocketwheelsKl on the former,.and K3 on the latter,

and an endless chain, K2.l The sprocket-wheelv K? is arranged torevol've loosely upon its axle, and can be slid longitudinally on the same by means of a shifting-levenvvhich is `pivoted on the frame, and extends forward to within convenient reach-of the driver. v

The hub of the sprocket-wheel is constructed with teeth, which engage with a clutch-lbox,

Kff, fastened permanently' on the axle.- A spiral spring-bears against the opposite` side ofthe sprocketiwheel, to'ass'ist in throwngfit into dgear with 'theclutch-box.

Two of radial reel-arms are provided withI rake-floats K5, which, by their sh'anks 7c, are adjustably secured between the two bars, which constitute the reel-arm, in Ysuch a man ner that the rake-heads can'be drawn'in'toy prevent them from raking the grain oh" of the platform. l

In thickgrain both lfloats'willbe used; but in thin grain onlyone of theml will" be ein-- ployed as arake.I

The reelil'oats are also adjustablyarranged 'between the 'bars of the lreel-a:rrns`,'so that they or drumsL2 audL1, the latterheing firmly se. cured upon the shaft I, by which the apron isl thus moved, traveling in thefdirection ofthearrow, away from the standinggr'ain.l

4To prevent "the grainfrom being'blow'n off" during its transit from the platform to the bind'ers car, the conveying-apron isprotected'f' fromthe wind-by a canvasicov'er, L3, stretched* over suitable bows, in the manner shown.

L4 represents fingers, arranged upon a shaft near the outer end of the conveying-apron in Y Y bearingsuponthesideboards of the frame- 'Ihe apron Hl is driven bythe upper shaft work",as" sh'ow'i in Fig. 4'.' These fingcrsoverhang the end of the apron, and serve to guide theIcutgra-in into? the receiver vbelow it, and their shaft is attached to a spring, L5, which holds it in the proper position, but permits of a partial rotation, that the ngers may yield to thevv pressurev of 'the"'grain and vallow it to drop The rear end of the machine is supported upon asmallv swiveling wheel, M,l whichisjatl' tached by a suitable clip tothe endof a longV liever, M1, and a shorter'swingingarth, M2. Both -the lever and arm are linked to themain "f frame A at'th'e lrear portion, thelformerat m and the latter va't m. The lev'erM1 extendsto' the forward end ofthe machine, 'and termi# hates in a metallic socket, in which 'a'short'f shaft isy arranged to're'volve', projecting asuf" ticient distance fromthe socket "to receifv''at its extreme end a crank-',M," and apiniionM".

cured upona 4post on the frame nearthdrivl ers seat, so that by 'turning the crahk 'in""on`e direction or theA other thelevt'er will lbe 'turned on lits fulcrum, and thus' elevate or depress the swivell'wh'eel M, whereby the "entire machine is tilted on 'its' lwheels B and D, so vas' lto I ele-v vate or lowerl theA` cutteribarQ'asi may 'b'required. Thehack of E the `rack Mserves' as a guide for ya hook form'edbnthejsocket'of the lever,by which meansfthpihiu is'held'in gear with the rack'. A' dog','M2', hinged to the crank, `is employed to hold the leveratahydef sir'ed elevation. ,e

The lever' M1 may' befoperate'dU by means'di'ff' ferent from those just described, Whiehwi'll readily 'suggest themselves "to thle'mind of an intelligent mechanic'. l

The machine'is conuiletel with thej above parts where'l the gaiuis'to be'drbpped in "ga'fi els upon the ground, and afterward" bound and shocked by bindersfollowii'ig it." Bnt 'If' have made provision for theattach'mentof' a" car luponv the side of the'machinefarthest'from the standing grain, for' the'reception'of thefv gavels, to have them bound' insuch' car, and discharged from the saine in numbers 'sufficient to form ashock.` This'loinde'rc'ar,I marked'Ng'. isfhinged to the side of "thefmainrame,so

that it vmay be' readily detached, extending under the conveyin,fg-ailrot. The vou'trside is supported upon a Vsmall wheel, N1',"as shown in I1`ig.-5.I Over the "body of the car' aa'w'i' ing, N2, is 'suspehdedupon posts', to screen the binders from the' rays" of 'tliefsuih andit" also has `a-table, N 3, extending from 'end toend,

'uponwhich the gavel's are boundi'j The binders ear 'canaccommoaate -itsff to" of the movements of''theirfai'n'frame,` and, 'bei-i ing attached to thelatter upon the sideopposite the reciprocating sickle and grain-platform, has a tendency to prevent the side d raft.

The gavels of grain drop from the conveying-apron into the receiver O, suspended below it -on the main frame, and detachably hinged to the latter.' In .the bottom of this receiver, which may beiconstructed as clearly shown in Fig. 4, a finger, O1, is arranged, pivoted upon a pin between ears ofy metallic plate The hub of 'the fin ger is made eccentric, and pressed upon by a spring, O3, underlying it, which will press the finger firmly down .into

its seat upon the bottom ofthe" receiver, as

shown in Fig. 4, aswell as hold it in the erect position when turned up, as shown in Fig. 1. The band or strand fory binding the gavel is placed across the receiver under the finger, which holds it iirmly in place, and on'removing the gavel the ngcr will be thrown up so that another band may be placed under it.v

P represents a short trough, which is hung by its hooks l? upon a bar of the main frame, and intended to carry the straw used for the binding of the gavels of grain.

The binding is completed by the binders, of whom two or more may be employed, upon the table N3, and thence the, sheaves are dropped into a hopper, Q, arranged upon the outside of the car. The inner side of the hopper, composed of slats :inclining from the table downward and outward, andl its ends are permanently secured to .the car. Its outer side is formed by one win g or the other of a revolving frame, Q1, which is journaled in bearings upon the top bars of the ends `of the hopper.

This frame is composed 4of a triangular axis, upon each side of which are bolted a series of slats, so as to form it with three Wings, the slats or bars of each wing being made of the proper length to extend to and be supported upon the sliding bottom of the hopper. This bottom Q2 is provided with an arm,g, at eachend, which arms are linked to the cranks g1 g1 ot' a rock-shaft, Q3. At q2 the roch-shaft carries another arm or crank, which is connected by a rod, g3, to an oscillating lever, Q5, pivoted upon a stud under the bottom of the car, and attached at its opposite end to a sliding bar, Q5. One end of the latter is at- Jcached to a foot-lever, Q6, which extends upward through the bottom of the car.

Whenever a sufficient number of sheaves have been collected in the hopper to form a shook, one of the binders presses upon this lfoot-lever, which, through the sliding bar, os

loillating-lever, and connecting-rod, oscillates the rock-shaft in such manner as to cause the bottom Nof `the hopper to be drawn inward from under the wing of the revolving frame Qi, resting upon it. The weight of the sheaves train of wheels, R1 R2 R3, driven by a pinion,l

It,'u`pon the driving axle, which wheels are 'arranged on the side of the main frame, di-

rectly opposite the inner end of the sliding bar Q5. The face of the last wheel R3 is con` structed with a cam, r, which, at each revolution of said wheel, pushes the sliding bar Q5 outward, to draw the hopper bottom from under the wing ofthe revolving frame. The speed of the wheel R3 with reference to the reel will be such that during each revolution of the former about twelve gavels of grain'will be delivered to the binders.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination of the concave elevating-apron H1 of the segmental grain-platform, and the ruhe-floats K5 of the reel, by the combined action of which the c'ut grain is elevated.

2. The spring-linger Ol O3, in combination with the receiver O, substantially as and for the purpose set forth.

3. The revolving frame Q1 and sliding bottom Q2 of the hopper Q, in combination with theoperating mechanism, composed of the cranked rockshaft Q3, connecting-rods q and g3, oscillating lever Q4, sliding bar Q5, and spring Q", substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
